Tucker Carlson sat down for a wide-ranging interview with President Trump during his trip to Michigan, where he discussed wiretapping, his tax returns and ObamaCare.

Regarding ObamaCare, Carlson asked whether Trump would deliver on his campaign promises of lower costs and better access for many in the country who need it, in light of conservatives' criticisms of the new legislation in its current form.

Trump said that if he had a plurality in the Senate, he could engineer a wider-ranging overhaul of the American health care system, but reiterated a point Speaker Paul Ryan (R-Wis.) made, in that certain items cannot be passed with a simple majority.

"I think we're going to have negotiations-- we only have 52 [Republicans], a two-vote margin," Trump said. "We're never going to have a Democratic vote."

"Why not wait?" Carlson asked. "You're the president. You have the ability to gather all the evidence you want."

Trump pointed to a New York Times story published about the campaign on Inauguration Day that used the term "wiretap," and also said several news programs floated reports about such surveillance.

Regarding his penchant for releasing information via social media, Carlson asked whether his Twitter messages are vetted by someone before he tweets.

Trump said that sometimes they are reviewed by his advisers, but added that many in the "fake press" do not cover his administration fairly, and that he can speak directly to the public through Twitter without the media's filter.

"I might not be talking to you right now as president if I didn't have a way of getting the word out," he said.
